I've managed to find sources for free tokens to stake on Stakecube - there are not a lot, but here's what I've found thus far:
https://allcoins.pw/?ref=61945 - PIVX and RDD
https://althub.club?ref=newby81 - PIVX and RDD
https://exchange-assets.com?ref=19609 - PIVX, RDD, SCC, PENG, SHARD, & PAC
https://www.thecryptofaucet.com/?r=15513 - BITB (Bean Cash)
Please let me know if you find others - thanks. Newby
